Wind-Informed Rapid Flight-Planning in Complex Urban Topologies via Machine Learning and Experimental Validation

Posted by klaurent Caltech

Kavli Affiliate: Morteza Gharib| Summary:Advanced air mobility operations hold the potential to enhance and expand regional transportation of both people and goods in populated areas. However, hazardous flight conditions arising from interactions between wind and the built environment remain a significant challenge for aerial vehicles in urban settings. This work proposes a novel framework towards […]

Semaphorin 3A promotes resilience of sleep and cognition to brain injury

Posted by dbos UCSF

Kavli Affiliate: Jeanne Paz | Authors: Deanna Necula, Yuliya Voskobiynyk, Srujana Poluri and Jeanne T. Paz | Summary: Chronic sleep disruption and cognitive deficits are debilitating long-term consequences of traumatic brain injury (TBI), yet the endogenous mechanisms that drive network-level recovery remain poorly understood. Here, we demonstrate that during the chronic phase post-injury, network oscillations […]

Design of ALPHA Phase I: A Plasma Haloscope for 10–20 GHz Post-Inflation Axions

Posted by klaurent MIT

Kavli Affiliate: Frank Wilczek | Summary:The axion is a well-motivated hypothetical particle capable of resolving both the strong CP problem and the dark matter mystery, with recent post-inflationary cosmological simulations favoring masses above 40 μeV. Plasma haloscopes serve as a promising experimental approach to reach theoretically preferred sensitivities in this mass range. ALPHA, hosted at […]

SMA Observations Reveal Abundant HNC Chemistry in Transition Disks

Posted by klaurent Peking

Kavli Affiliate: Feng Long| Summary: The physical and chemical conditions of protoplanetary disks shape the properties of nascent planetary systems. The line ratios and relative abundances of the HCN-HNC isomer pair are well-suited for tracing these gas conditions, since isomer chemistry is linked to the underlying temperature, elemental abundances, and irradiation environment of the emitting […]

Discovery of four Narrow-line Type-1 Quasars at z = 2.54 — 6.06 with Subaru ‘Onohi’ula PFS-SSP

Posted by klaurent Tokyo

Kavli Affiliate: Khee-Gan Lee | Summary:We report the discovery of four narrow-line type-1 quasars (NLQ1s) from the Subaru ‘Onohi’ula Prime Focus Spectrograph Subaru Strategic Program (PFS-SSP). To extend a comprehensive understanding of this population to the distant universe, we searched for broad-line AGNs (quasars) whose rest-UV spectral shapes resemble those of local NLS1 galaxies, utilizing […]

A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion

Posted by klaurent Stanford

Kavli Affiliate: Bruce Macintosh | Summary:AF Lep b is one of the closest analogs to Jupiter in terms of mass ($3-4~M_rmJup$) and semi-major axis ($9$ AU) amenable to spectroscopic characterization. We present JWST/NIRSpec high-contrast spectroscopy of the planet from $2.85-5.3~μ$m at $Rsim3000$, which provide detections of CO$_2$, H$_2$S, CH$_4$, $^12$CO (and $^13$CO), and H$_2$O, as […]
